Teach4n Reveals How Pollut�on
.
A drastic reduction in mo-
tor vehicle emissions — by as
much as 55 per cent on the
average -- may be achieved,
if only car owners tune up
their vehicles for low emis-
sions.
That is one of the major
findings reported by a group
of •University of Michigan en-
gineering students who con-.
ducted an emission tune-up
clinic during the Environ-
mental Teach -In here last
spring.
'
More than 85 percent of
the cars. the students said,
showed a decrease iii hydro-
carbon emissions following a
tune-up (spark plugs, points,
ignition timing and carbure-
tor adjustments) The car-
bon monoxide and unburned
hydrocarbon' -emissions were

reduced by an average of 55
percent at idle, the U ;M stu-
dents reported. A car, at idle,
releases the greatest concen-
tration of emissions.
"Sortie cars came in with
seven tp ten per cent carbon
monoxide in the exhaust and
left with a fraction of a per,
c nt. Some had unburned
lrocarbon concentrations
of 3,000 parts per million
which were reduced to sev-
eral hundred parts," the Stu-
dents said.
"The data indicate that
pre -1968 cars have much
higher, average hydrocarbon
emissions than post -1968
cars shbwing the same mile-
age."
These and other data have
led the U -M students to ob-

Benefit from M�torTun.e

Auto Editor, Kansas City Star
It's the same old song they sing all the time.
"Get a tuncl up. It's cheaper ' in the long run. It will pay
for itself in gas saved. It will pay for itself in performance.
It will pay for itself in a longer -lasting engine.
Those who sing the song are the ones who do the tuning -up
and sell the sparkplugs. It is what everyone expects them to.
say. Is it really true?
Disinterested third parties are not easy to find, but two
experts from San Bernardino, Calif., say it is true — and
they don't sell spark plugs or do tune-ups. ,
They are in the automotive pollution testing business, not
for the industry but for the federal government. They say it is
all true and theyadd a benefit of their own:
Tune-ups contribute to longer human life through cleaner
exhaust gases.
New Rigors Short
In the old days, the richer
gasoline mixtures served to
cool the combustion cham-
bers and render an easier
explosion, even if large quan-
tities of unb°nrned hydrocar-
bons were: dumped into the
air.
The new rigors inside the
combustion chamber also

experts pointed out, one
SLOWPOKE DANGEROUS
The slowpoke on the ex -
'!w pressway is just as danger-
ous as the speeder. If traffic
streams past you or you are
- leading a slow parade in your
lane, speed up or get ,.off the
expressway. You are a haz-
ard when you block traffic.
STOP 1VIE IF YOU'VE
HEARD THIS . ,
Stopping a car on dry
pavement at 20 miles per •
hour .requires 17 feet of dis-
tance. At the same: speed on
ti glare ice, the distance re-
quired is 149 feet with regu-
lar tires and 120 feet with
studded snow tires. Slow

standard V-8 engine.
Air filters and idle settings
on the carburetor also are
critical to economy, per-
formance and clean exhaust,
they said.
A technician at Olson Labdratories tests emissions in an attempt to relate air pollution to motorists'
maintenance habits. Use of new anti -pollution devices makes proper engine 'care even more vital
for top performance and dependability.
A dirty air cleaner element
